An exact viscosity solution to a Hamilton–Jacobi–Bellman quasi-variational inequality for animal population management
Autor: Yuta Yaegashi, Hidekazu Yoshioka, Kentaro Tsugihashi, Masayuki Fujihara
Publikováno v: Journal of Mathematics in Industry, Vol 9, Iss 1, Pp 1-26 (2019)
Abstract We formulate a stochastic impulse control model for animal population management and a candidate of exact solutions to a Hamilton–Jacobi–Bellman quasi-variational inequality. This model has a qualitatively different functional form of th

Stochastic optimal switching model for migrating population dynamics
Autor: Hidekazu Yoshioka, Tomomi Tanaka, Futoshi Aranishi, Tomoki Izumi, Masayuki Fujihara
Publikováno v: Journal of Biological Dynamics, Vol 13, Iss 1, Pp 706-732 (2019)
An optimal switching control formalism combined with the stochastic dynamic programming is, for the first time, applied to modelling life cycle of migrating population dynamics with non-overlapping generations. The migration behaviour between habitat

Nonlinear growth dynamics of date palms responding to environmental parameters
Autor: Koichi Unami, M. Yamaguchi, E.J. Magero, Osama Mohawesh, Masayuki Fujihara
Publikováno v: Supplementary 6. 4:60-63
Scientific analysis of plant growth helps in improving the efficiency of cultivation practices through optimization of their environmental conditions. The ultimate aim of this research was to derive an optimal policy for better growth of date palms b

Biological population management based on a Hamilton–Jacobi–Bellman equation with boundary blow up
Autor: Hidekazu Yoshioka, Yumi Yoshioka, Yuta Yaegashi, Masayuki Fujihara
Publikováno v: International Journal of Control. 95:50-67
Establishment of a long-term biological population management policy requires balancing its cost and utility/disutility. We approach this issue from the viewpoint of stochastic control as an effici...

Prototype and model of solar driven desalination plant in arid environment
Autor: Masayuki Fujihara, Koichi Unami, Osama Mohawesh
Publikováno v: Thermal Science, Vol 24, Iss 2 Part A, Pp 903-914 (2020)
Water shortage and salinity are crucial factors affecting plant growth in arid and semi-arid regions, where irrigation water shortage and capillary rise from shallow saline water tables are often encountered. The objectives of this study are to const
